PATENT FRANK BATEMAN, OF SPRING MILLS, NEW JERSEY, ASSIGNOR OF ONE- HALF TO EDWARD S. BATIJMAN, OF SAME PLACE.

CULTIVATO R.

SPECIFICATION forming part of Letters Patent N0. 240,945, dated May 3, 1881.

Application filed November 22, 1880.

To all whom it may concern Be it known that I, FRANK BATEMAN, a citizen of the United States, residing in Spring Mills, Camden county, New Jersey, have invented certain Improvements in Cultivators, of which the following is a specification.

The objects of my invention are to provide a cheaper and more effective means than the usual roller for pressing down the ridge of earth thrown up by the covering-blades, and to so hang a weed-cutting blade to one of the side bars of the cultivator-frame that the said blade may be adjusted to any desired position.

In the accompanying drawings, Figure l is a perspective view of part of the frame of a cultivator with my improvements; and Figs. 2, 3, and 4 detached views of parts of the same.

The frame of the cultivator consists, as usual, of the central bar, A, and opposite side bars, B B, said bars being bolted at the front ends to a suitable head-stock, and being adjustably connected at the rear ends by means of the bars a and clampsb.

It has not been deemed necessary to illustrate the draft apparatus, the usual blades of the cultivator, or the handle-bars, as these form no part of the invention.

To the rear end of the bar A is bolted a U- shaped bar, d, both standards of which are provided with a series of perforations for the reception of retaining-bolts. The rear standard of the bar d is connected to the back of a plate, I), which is widest at the rear end and is tapered toward the front, the plate being curved longitudinally, and having a concave under surface and comparatively sharp edges, so that as the machine is drawn forward the plate will press upon the top of the ridge of earth thrown up by the blades, and will properly compact the same,thereby performing the duty which ordinarily demands the use of a roller. The plate D is much lighter and is less expensive than a roller, and is more effective in its operation, moving easily over the ground, and being free from liability to clog.

The entire plate may be elevated or depressed when necessary by shifting the confining-bolts in the openings of both standards of the bar (I; or, if it is desired to elevate or depress the rear end of the blade to a greater extent than justment of the blade F is possible.

(No model.)

the front end, one of the bolts may serve as a pivot, on which the bar can swing.

To the side bar, B, of the frame is secured by means of a pivot-bolt, e, a bent plate, E, the laterally-projecting portion of which has an opening adapted for the reception of the stem of a bolt, f, one end of the latter being bent so as to form an eye, g, and the opposite end of the bolt being threaded for the reception of a nut. (See Fig. 4..) A washer, m, recessed for the reception of a portion of the eye g, is interposed between said eye and the plate E, so as to afford an extended bearing-surface.

To the eye g is adapted the stem a of a curved blade, F, the front edge of which is sharpened,so that as it is drawn along the side of a row of plants it will work close up to said row, and will cut away the weeds which have not been uprooted by the cultivator-blades in advance, thus accomplishing the work of. the hand-hoes ordinarily employed.

Owing to the work performed by the blade F, accurate adjustment of the same becomes desirable, and this is effected in my machine by the use of the bent and pivoted plate E and the eyebolt f, for by this means universal ad- The blade is adjusted vertically by shifting the stem at of the blade vertically in the eye g, and then tightening the nut, so as to clamp the said stem against the washer. The stem may also be turned in the eye of the bolt so as to cause the point of the blade to move in the arc of a circle of which said stem is the center, and the entire blade may be caused to swing laterally by turning the bolt and washer in one direction or the other, so as to throw the blade toward or from the bar B.

The pitch of the blade may be governed by turning the plate E on its pivot-pin, and in or-- der to secure the platein any position to which it is adjusted, 1 enlarge the rear end of said plate and provide the same with a series of openings, to anyone of which may be adapted a confining-bolt, s.

A blade, F, may be used in connection with the opposite side bar, B, of the frame, also, if desired; or said bar may be furnished with the usual cultivator-blade.

I claim as my invention- 1. The combination of the bar A of the frame, the presser-plate D, the U-shaped bar (I, having openings in both standards, and the bolts for confining the same, as specified.

2. The combination of the side bar of the frame, the bent plate E, bolted to said bar, the cutting-blade F, having a stem, at, and the bolt f, adapted to an opening in the laterally-projecting portion of the plate E, and having an eye, 1, for the reception of the said stem n of [O the blade, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
